d27ef5bf6f cpu/x86/mp_init: use cb_err as mp_init_with_smm return type
Using cb_err as return type clarifies the meaning of the different
return values. This patch also adds the types.h include that provides
the definition of the cb_err enum and checks the return value of
mp_init_with_smm against the enum values instead of either checking if
it's non-zero or less than zero to handle the error case.

* Decomposed components from CSE FPT file: RBEP, MFTP.
* Input components: PMCP, IOMP, NPHY, TBTP, PCHC.

BP2:
* Dummy components: DLMP, IFPP, SBDT, UFSP, UFSG, OEMP, ISHP.
* Decomposed components from CSE FPT file: RBEP, FTPR, NFTP.
* Input components: PMCP, IOMP, NPHY, TBTP, PCHC, IUNP.

6ef863c5c4 soc/intel/common/cse: Add support for stitching CSE components
This change adds support for allowing mainboards to stitch CSE
components during build time instead of adding a pre-built CSE
binary. Several Kconfig options are added to allow mainboard to
provide the file names for different CSE region components. This makes
use of the newly added cse_serger and cse_fpt tools to create
following partitions:
1. BP1 - RO
2. BP2 - RW
3. Layout

In addition to this, it accepts CSE data partition as an input using
Kconfig CSE_DATA_FILE. All these partitions are then assembled
together as per the following mainboard FMAP regions:
1. BP1(RO) : CSE_RO
2. BP2(RW) : CSE_RW
3. Layout  : CSE_LAYOUT
4. Data    : CSE_DATA

Finally, it generates the target $(OBJ_ME_BIN) which is used to put
together the binary in final coreboot.rom image.

Several helper functions are added to soc/intel/Makefile.inc to allow
SoCs to define which components use:
1. Decomposed files: Files decomposed from Intel release CSE binary in
FPT format.
2. Input files: Mainboard provided input files using corresponding
Kconfigs.
3. Dummy: Components that are required to have dummy entries in
BPDT header.

These helpers are added to soc/intel/Makefile.inc to ensure that the
functions are defined by the time the invocations are encountered in
SoC Makefile.inc.

including `SkipMpInit=0`, `SkipMpInit=1`, use of the MP PPI or FSP
Multiphase Init. This way full control is left to coreboot.

5c259642c2 soc/intel/{common,skl}: set ACPI_FADT_PLATFORM_CLOCK based on Kconfig
The FADT contains a flag `ACPI_FADT_PLATFORM_CLOCK` telling the OSPM if
a specification-compliant PM Timer is present. Currently, this flag is
set regardless of the timer being enabled or disabled.

To be specification-compliant, only set that flag, when the hardware PM
Timer is enabled. This changes behaviour of all mainboards defaulting to
USE_PM_ACPI_TIMER=n.

Note: On platforms supporting uCode PM ACPI Timer emulation, this is
      required, too, because emulation does not support `TMR_STS`. Any
      OS or software checking this flag and thus relying on the overflow
      flag would not work (properly).

d2da870499 soc/intel/common/cse: Split CSE metadata into two CBFS files
This change splits CSE metadata structure (added to CBFS) into two
separate CBFS files (me_rw.hash and me_rw.version). Since `struct
cse_rw_metadata` is now used, it is dropped completely.

This change is being made in order to prepare for the upcoming changes
to stitch CSE binary at build time. Since the binary might not be
available pre-built, it complicates the order of operations for the
addition of CSE metadata structure and declaring hash and version as
CPPFLAGS_common. Instead rules can be enabled for individual CBFS file
targets for hash and version that ensure proper ordering as well.

BUG=b:184892226
TEST=Ensured that update works correctly on brya by forcing version
mismatch. In case of version match, no update is triggered.

c45e0bedb2 soc/intel/common/cse: Reorganize firmware update checks for CSE Lite
`cse_fw_update()` is currently checking whether an update is required
by comparing versions once and then again comparing versions later in
`cse_is_downgrade_instance()` to determine if the update is an upgrade
or downgrade. Additionally, if CSE RW partition is corrupt (determined
based on `cse_is_rw_bp_sign_valid()`), `cse_is_downgrade_instance()`
ends up using the corrupted version information to determine if it is
a downgrade instance.

This change reorganizes the firmware update checks to return different
status values:
1. CSE_UPDATE_NOT_REQUIRED: No update required. Versions match.
2. CSE_UPDATE_UPGRADE: Update required and it is an upgrade.
3. CSE_UPDATE_DOWNGRADE: Update required and it is a
downgrade (requires data clear).
4. CSE_UPDATE_CORRUPTED: `cse_is_rw_bp_sign_valid()` failed and hence
requires data clear.
5. CSE_UPDATE_METADATA_ERROR: Unable to read CSE metadata from CBFS.

This change also prepares the file for follow up changes which
completely drop cse_rw_metadata structure.
